Nevertheless, the terror which prevailed in the last years of Tiberius, to whomsoever it is chiefly to be ascribed, exercised a baleful influence over society at Rome, and shows by effects which are still discoverable that it has been but little exaggerated. It has left permanent traces of itself in the manifest decline and almost total extinction of literature under its pressure. The Roman writers addressed only a small class in the capital; to be popularly known in the provinces, to be read generally throughout the Roman world, was a privilege reserved for few, and anticipated perhaps rarely by any. Even in the capital the poet and historian composed their works for a circle of a few thousand knights and senators, for the friends and families of their own few hundreds of acquaintances, whom they invited to encourage their efforts by attending their recitations. The paralysis which benumbed the energies of the Roman nobility at this crisis of terror and despair, extended naturally to the organs of their sentiments and opinions. Not history and philosophy only suffered an eclipse, but poetry also, which under Augustus had been the true expression of the national feelings, became mute when the feelings themselves could no longer be trusted with utterance. Cremutius was subjected to persecution for pronouncing that Brutus and Cassius were the last of the Romans. A tragedian was accused, and if accused, we may presume, perhaps, that he was condemned for speaking evil of the king of men, Agamemnon; and various authors were assailed, and their writings sentenced to proscription, to whose recitations the last princeps had himself listened with indulgence. The poems which were tolerated were generally the most trifling, and perhaps licentious in character. The sly irony of the fable, a style of composition adopted by slaves, and imitated from the servile Orientals, seems not unsuitable to these perilous times. The name of Phædrus belongs in all probability to the Tiberian period, but it is curious that no later writer for four centuries should have cared to notice him. Similar or worse has been the fate of a more serious writer, Manilius, the author of an elaborate poem on astronomy and its spurious sister astrology, a theme of some danger under the circumstances of the times, but which he has treated with irreproachable discretion; it is owing, perhaps, to the disgrace under which the forbidden science fell that this innocent work lapsed into entire oblivion, and has escaped the mention of any writer of antiquity.
